Dr. Dan Hahn joined the Gainesville faculty as an Assistant Professor specializing in Insect Physiology. His appointment is 50% research and 50% teaching with instruction responsibilities including a graduate course in insect physiology and graduate and undergraduate courses on selected topics in entomology and biology. Dan's research integrates physiology, biochemistry, and evolutionary ecology to address a range of questions in insect biology. Current topics of interest are: 1) physiological mechanisms underlying phenotypic plasticity in insects with a focus on diapause and reproduction, 2) regulation of metabolism and nutrient allocation in insects emphasizing the regulation of storage and subsequent utilization, 3) insects as model systems to study fertility, diabetes, and obesity. Dan received his B.S. from Florida State, his Ph.D. from University of Arizona, and comes to Gainesville from a postdoctoral fellowship at Ohio State. Dan is joined by his wife Jen, a biologist and science educator, and their toddler Ben.
On 12 December 2004, graduate student Ricky Vazquez was commissioned a First Lieutenant in the U.S. Army Reserves. He served as an enlisted Marine from 1989 to 1993, when he was a communications center operator. Now he is the medical entomologist for the 342nd Army Medical Detachment in Gainesville, but plans to go on active duty at the conclusion of his Ph.D. studies.
Olga Kostromytska is a new M.S. student working with Dr. Buss. Obviously, Olga is interested in landscape and turfgrass entomology, but she is specifically interested in white grubs, especially Tomarus subtropicus.
Suzie Adams began work as a Fiscal Assistant in the business office during December. After a period of training, she will handle credit card payments and travel.
Jay Cee Turner, who received her M.S. working under Dr. Eileen Buss, will start working as a Biological Scientist for Dr. Oscar Liburd as of 10 January.

Tara Tobin Cataldo is the new Biological/Life Sciences Librarian at the Marston Science Library. She attended the December entomology and nematology faculty meeting and gave a presentation on changes at the library and the services they offer. Some of the information she presented is available at http://www.uflib.ufl.edu/msl/entfac.html. A listing of new books in biological science added by the Library is available at http://web.uflib.ufl.edu/msl/newbooksbio.html. You may contact Ms. Cataldo at (352) 392-2784 or firstname.lastname@example.org.
For her M.S. degree, Sue Gruner conducted the largest forensic entomological decomposition study (to date) using pigs as human models. Over a four year period, sixty-nine pigs were placed out at Greathouse Butterfly Farm in Earleton, Florida. One of the first species of Calliphoridae to arrive at a corpse (in approximately 1/3 of the U.S.) is Lucilia (= Phaenicia) coeruleiviridis. When L. coeruleiviridis larval specimens are found at a crime scene, forensic entomologists historically have used the phenology from L. sericata, a closely related species, to determine time since death because there are no rearing data for L. coeruleiviridis. Successful rearing of this particular species of fly has eluded entomologists for decades, but Sue "discovered" a pupation substrate, using organic materials and a mulching machine, that resulted in successful rearing of thousands of adult specimens. In July 2004, Sue attended the Second Annual North American Forensic Entomology Conference held at UC-Davis, California, and presented her M.S. research data, which included information about the pupation substrate. Among the attendees were forensic entomologists from Europe, Australia, Canada and South America and Richard Merritt, president of the American Board of Forensic Entomologists (ABFE).
In October 2003, the body of an 11 year old girl, who had been missing for a month, was found behind an old, vacant factory in Cleveland, Ohio. As usual in many crime scenes, the police did not know what to do with the entomological evidence. A zoologist was hired to collect entomological specimens during the autopsy - evidence that should have been collected at the crime scene. The live larval specimens did not survive so the zoologist assumed they were L. coeruleiviridis. He also had some poorly preserved specimens in alcohol which were later identified by Neal Haskell (for the defense) as L. coeruleiviridis. On 6 December 2004, one of the prosecuting attorneys called Dr. Merritt to determine which ABFE member was the "expert" on L. coeruleiviridis. However, there being none, Dr. Merritt referred the prosecutor to Sue Gruner, who is an expert due to her research. Shortly thereafter, Sue flew to Cleveland where she testified for the first time as an "expert witness." Her testimony centered around the behavior and biology of L. coeruleiviridis.

The Reading Room committee once again reminds us that no one is allowed to take materials out of the reading room, and no one is allowed to take food or drink in. You are also reminded that Reading Room users are monitored on closed-circuit TV, so wave and say hi. In addition, the committee asks that you to tidy up after yourself before leaving the room. Those who wish to use the in-room copier should visit the stock room to get a PIN from Nick Hostettler.
Caterpillar: Pilare is the Latin for "to grow hair" and gives an adjective pilosus, meaning "hairy." From this and their own word chat, a cat, the French formed chatepelose, "hairy cat," which may be compared to "wooly bear," the common name by which English children refer to the same fuzzy creature, the caterpillar. The French word, chatepelose, was in due course taken into English; but the significance of the latter part of the word was not recognized. It was actually confused with the stem of the old English word "to pill," meaning "to strip or plunder," the idea being that the caterpillar strips the bark (leaves? - ed.) off trees. This is the reason why the spelling of the word has departed so far from the French form. - from Thereby Hangs a Tale: Stories of Curious Word Origins by Charles Earle Funk
Scientists have developed a robot that powers itself by eating house flies, but they need some help determining the correct species of fly (as you will see in the photograph), let alone how to write the common name.
